Clinical characteristics and medication patterns in patients with COPD prior to initiation of triple therapy with ICS/LAMA/LABA: A retrospective study.

Abstract

This study assessed patient-level characteristics and patterns of medication use in patients with chronic obstructive pulmonary disease (COPD) before initiation of multiple inhaler triple therapy (MITT; long-acting muscarinic antagonist/long-acting β2-agonist/inhaled corticosteroid [ICS/LAMA/LABA] combination). This retrospective study was conducted using the Optum Research Database. Patients enrolled in commercial or Medicare Advantage Prescription Drug plans, with a COPD diagnosis and >1 prescription for a COPD medication between January 2014 and March 2016 were included. The dispensing date for the first pharmacy prescription completing MITT with at least 1 day of overlap was the patient's index date. The 12 months prior to this date were used to assess patient characteristics, exacerbations, eosinophil counts and changes in medication. The study population comprised 13,701 patients. At the index date, most patients were using a LAMA (n = 13,353 [97.5%]) and combination ICS/LABA (n = 13,292 [97.0%]) MITT. Overall, 90.4% of patients used a LABA, LAMA, LAMA/LABA, or ICS/LABA or had a moderate or severe exacerbation at any time during the baseline period, indicating that approximately 10% of patients initiated MITT without prior bronchodilator use or exacerbation history. Over 65% of patients with an eosinophil measurement had a value ≥ 150 cells/μL. Overall, it appears that in this patient population, ICS/LAMA/LABA as triple therapy is being initiated after use of a bronchodilator and/or after an exacerbation event, in accordance with accepted treatment recommendations.
